of occupation of the site at Dolebury Warren. These include flintwork from the Palaeolithic, bronze spearheads, Bronze Age pottery, and Roman pottery and coins. There is evidence of occupation of the site during the Iron Age. The defences and Celtic field systems there date back to the 7th century−3rd century BCE, though they might mask earlier developments. The hillfort was occupied until approximately 100BC, though it is possible that it was reoccupied in the Roman and post-Roman periods. The archeological consultant Peter Leach has suggested there may even have been a Roman Temple built within the hillfort, while aerial photographs suggest the probable remains of an Iron Age or Roman coaxial field system. Local historian Robin Atthill also suggests that Dolebury may have re-emerged as an important centre of population in the 5th century. Medieval In the medieval or post-medieval period, the remains of the hillfort were used as a rabbit warren which was used to breed rabbits, providing valuable meat and fur. Many warrens were surrounded by banks or walls to prevent the rabbits from escaping; escaped rabbits caused damage to nearby farmland and meant a loss in profit. The warren at Dolebury is completely enclosed by the substantial ramparts of the Iron Age hill fort and thus provided an ideal location to breed rabbits. The presence of pillow mounds and vermin traps demonstrate management of the site for husbandry. Ridge and furrow agriculture has also been identified, from aerial photographs, within the fort. Some of these structures, along with earlier Iron Age features, have been damaged by subsequent quarrying which may have been for lead, ochre or calamine. The site was described by John Leland in the 16th century. A three-storey building, believed to be the warrener's house and possibly a watch tower, surrounded by a garden, was in ruins by 1830. 19th and 20th centuries The site was visited in the early 19th century by John Skinner and surveyed in 1872 by Charles William Dymond. In 1906 the Mendip Lodge Estate, which included Dolebury Warren, was sold. It was first scheduled as an ancient monument in 1929. In 1935 Dolebury Camp was bought by Miss V. Wills of the W.D. & H.O. Wills tobacco company to prevent development. Dolebury Warren was notified as a Site of Special Scientific Interest in 1952. The freehold of was acquired by the National Trust in 1983 from A. G.
